[Problems with Ureteral Stents – a Never-Ending Story].

Temporary drainage of the upper urinary tract by internal ureteral stents is a common procedure to assure renal function and to treat pain caused by ureteral obstruction. Ureteral stents are frequently associated with side effects like urinary symptoms, pain or hematuria resulting in frequent medical consultations. In addition to good patient education, symptomatic drug therapy of stent-associated symptoms is often indicated and sufficient. However, complications like stent dysfunction or significant urinary tract infections have to be kept in mind, as they require further diagnostics and treatment. Therefore, especially general practitioners as a primary point of contact for the patients should be familiar with common ureteral stent-associated problems, their treatment and indications for patient referrals.
